Fabrication method of soft mold for barrier rib in plasma display panel and method of forming barrier rib using the soft mold

摘要

PURPOSE: A method for producing a soft mold and a method for forming barrier ribs are provided to increase yield rate of a plasma display panel by preventing the camber or damage on a glass substrate, while minimizing the damage on barrier rib patterns during the removal of the mold. CONSTITUTION: A method for producing a soft mold for formation of barrier ribs of a plasma display panel, comprises a first step of depositing a photoresist on the surface of a rear surface substrate(30); a second step of forming a basic mold frame by forming photoresist patterns through the use of a photomask where barrier rib patterns are formed; a third step of injecting a molten silicon rubber into the basic mold frame; a fourth step of solidifying the silicon rubber; and a fifth step of separating the solidified silicon rubber from the basic mold frame.
